Chiming in here. I drove @
brzsubie's car and there is oversteer but the more pressing matter is that the dampers aren't critically damped and making the car unpredictable during hard driving. To my feel, the car is neutral but the car is unsettled easily. We dialed the front to 12 from full soft and the rears 15 from full soft. These settings felt compliant enough for the backroad we were driving on but the dampers feel underdamped on rebound. Compression felt fine.
What would help is if someone with Flex As and track experience chimed in with their settings to get us started with dialing in the shocks.
Thanks.
